Looking to take the train from Domodossola Italy on the route that goes through Brig, Goppenstein, Spiez. Then from Spiez to Interlaken Ost. (I will aiming to take the train that avoids the second tunnel) Is this a scenic trip? How does it compare to the Bermina Train route? I had originally planned to take the Bermina route but it does not work as well with the flow of my trip.
edit- another option is for me to fly into Geneva, make my way to Interlaken Ost by travelling through to Montreux through Zweisimmen to Spiez. Is this train trip from Montreux to Spiez a scenic trip? That would satisfy the fact I am missing out on Bernina.
Thanks!
